The isothermal section of the phase diagram of the ternary system La-Ni-Nb at 673 K has been investigated by X-ray diffraction, differential thermal analysis, optical microscopy, and electron microscopy techniques. It consists of 14 single-phase regions, 25 two-phase regions, and 12 three-phases regions. At 673 K, the maximum solid solubilities of Nb in Ni, LaNi5, LaNi7, LaNi3, La7Ni16, and LaNi3 is about 3, 5, 2, 3, 3, and 2 at.% Nb, respectively. The composition range of the Nb in NbNi3 is about from 23.5 to 27 at.% Nb. No ternary compounds were observed. (C) 2004 Elsevier B.V. All rights reserved.
